Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a photographic printing apparatus, and more particularly to a photographic printing apparatus adapted to print a frame number of a negative film frame corresponding to the back side of a printed photograph. It is a thing.

[Conventional technology]

Most of photographed negative films are usually transferred to simultaneous printing in which film development and printing are performed. In this simultaneous printing, first, a negative film is developed, and then each frame recorded on the negative film is printed and exposed on photographic paper to obtain a print photograph. Further, the negative film that has been printed and exposed is cut into, for example, every six frames to form a negative piece, which is loaded into the bag portion of the negative sheet. Then, the negative sheet and the print photograph are stored in a DP bag and given to the customer.

In the above print processing, the average transmission density (LA
TD), and the basic printing exposure amount of three-color light is calculated from the average transmission density. However, only about 70% of the total prints that can be printed with the proper density and color balance can be made with this basic printing exposure amount alone. Inappropriate. Therefore, for the frame in which the subject ferria occurs, the operator's experience determines the exposure correction amount of yellow, cyan, magenta, density, etc., and corrects the basic printing exposure amount.

By the way, in the simultaneous printing, one print photograph is produced for one frame of the negative film, and when a plurality of print photographs are required, a request for additional printing is made. In this reprint printing, the operator is often different from the simultaneous printing, and the exposure correction amount is slightly different even for the same operator. For this reason, in the case of the conventional additional print, the finish in the same state as the simultaneous print is rarely obtained.

On the other hand, in order to easily create additional prints of the same density and color balance as the print photo obtained by simultaneous printing, the frame number is printed on the back of the print photo and the negative piece stored in the negative sheet is printed. Japanese Patent Application No. 1-181446 and Japanese Patent Application No. 1-265466 have disclosed a frame number printing system that prints a frame number and an exposure correction amount on a negative sheet in accordance with the position of each frame. The applicant has proposed.

[Problems to be Solved by the Invention]

However, the above-mentioned system is made long by connecting a large number of negative films so as to be suitable for a large-scale developing station which processes a large number of simultaneous prints, and is used for efficient developing processing. For this reason, a dedicated film splicing device, a printer, and a film cutting inserter are required, resulting in a large device configuration. Therefore, in a small-scale photo lab that prints on a one-off basis,
There is a problem that it is difficult to introduce the frame number printing system.

SUMMARY OF THE INVENTION The present invention is intended to solve the above problems, and an object of the present invention is to provide a photographic printing apparatus capable of easily implementing the frame number printing system even in a small-scale development laboratory.

[Means for solving the problem]

In order to achieve the above object, the present invention provides a means for setting each frame of a photographic film at a print position, and a film feed amount and a frame number bar code detection signal at the time of setting the frame set at the print position. A means for specifying a frame number to obtain frame position data, a means for printing the frame number on a print frame of photographic paper based on the detected frame number, and a photographic film cut into film pieces based on the frame position data. Specify the cutting position for
A means for recording the cutting position on the photographic film, and when the photographic film is cut at the cutting position and inserted into the film sheet, each frame is arranged in the same arrangement as each frame position of the photographic film in the film sheet. And a print printer for printing the frame number and the exposure correction data used during the printing exposure on the reordered sheet.

[Action]

When printing simultaneously on a printer processor used in a small-scale photo lab, each frame of the negative film is automatically or semi-automatically moved to the print position by the film carrier (the operator operates the frame feed key to perform negative feed). ) Is set. As is well known, automatic frame setting to the print position is performed based on the edge detection timing of each frame by the screen sensor during the transfer of the negative film and the edge detection timing and the film feed amount.
When the frame is set to this print position, the frame number bar code recorded on the side edge of the film is detected, and the frame position bar code is detected and the bar code read signal and the film feed amount are used to determine the print position. The frame number of the set frame is specified. afterwards,
The operator inputs the exposure correction data by observing the image of the frame set at the print position. After this,
Printing exposure is performed.

Then, the cutting position of the photographic film is specified based on the frame position data specifying the position of the frame for each frame number, and the cut mark is recorded on the photographic film based on the cutting position. Then, the photographic film is cut into film pieces based on the cut marks and inserted into the film sheet. A reorder slip is printed based on the cutting position and frame position data. This reorder ticket
When the film piece obtained by cutting the film with the cut mark is inserted into the film sheet, the frame number and exposure correction data are printed in the same arrangement as each frame, so it is possible to find the frame when reordering. It becomes easy and the exposure correction data used at the time of simultaneous printing can be easily obtained.

〔Example〕

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a schematic diagram showing the configuration of a printer processor 10 used in a small-scale development laboratory or the like. FIG. 2 is a perspective view showing the appearance of the printer processor 10 and the print printer 11 connected online thereto. The printer 11 is
Re-order slip based on print data from printer processor 10
Print 12. The print printer 11 is configured in the same manner as a normal word processor printer, and is capable of printing front characters in addition to printing characters and symbols.

As is well known, the printer processor 10 is composed of a printer unit 13 and a processor unit 14. Printer section
The reference numeral 13 illuminates the print target frame of the negative film 15 set at the print position 19 by the film carrier 20 with the light from the light source 23 which is dimmed by the filter adjusting unit 21 and homogenized by the diffusion box 22. The image of the selected frame is printed and exposed on the color paper 26 through the printing lens 24 and the shutter 25. A printing device 28 is arranged on the exit side of the exposure position 27 of the color paper 26. The printer 28 prints a frame number on the back surface of the color paper 26 which has been exposed by printing, at a position corresponding to each print frame. As is well known, the processor unit 14 includes a color developing tank, a bleach-fixing tank, a washing tank, a drying unit, and the like, and performs development processing by guiding the printed and exposed color paper 26 into each processing tank. Color paper 26 after development processing is cut into each frame, and printed photo 29
Are accumulated in the saucer 18 as.

The film carrier 20 is for automatically setting the negative film 15 at the printing position 19, and includes three pairs of feed rollers 30 for feeding the negative film 15, and a pulse motor 31 for controlling rotation of the pair. Is equipped with. The pulse motor 31 is controlled by a controller 33 via a driver 32. A film sensor 34, a film tip sensor 35, a screen sensor 38, and a frame number bar code sensor 39 are sequentially arranged on the film entrance side of the film carrier 20, and signals from these sensors are sent to the controller 33. .

The film sensor 34 detects whether or not the negative film 15 is set on the film entrance side of the first film feed roller pair 30. The film leading edge sensor 35 detects the leading edge of the negative film 15 during the transfer of the film. Further, the screen sensor 38 detects the edge of each frame 15A from the difference in density between each frame 15A of the negative film 15 and the blank portion 15B between each frame 15A as shown in FIG. The frame number barcode sensor 39 detects the frame number barcode 15C recorded on the side edge of the negative film 15. Incidentally, reference numeral 37 in FIG.
Shows a check tape having an ID number attached to identify the negative film 15 from those of other orders.

Further, as is well known, a scanner 43 for performing three-color separated photometry on each point of the frame is arranged at a position facing the frame to be printed on the film carrier 20, and a signal from the scanner 43 is used as an exposure amount calculation unit 44. Sent to. The exposure calculation unit 44
First, characteristic values such as the LATD of the frame and the color correction coefficient value are calculated, and the exposure control value is calculated by a well-known arithmetic expression based on these characteristic values and the exposure correction data input by the negative test as necessary, This is sent to the controller 33. In the negative test, the operator observes each frame, and operates a density key, a color correction key, a function key, a correction key, etc. of the keyboard 33A for a satisfactory result when the basic exposure based on the LATD does not produce a satisfactory result. This is performed by inputting exposure correction data.

Further, a cut marker 46 is provided on the film exit side of the print position of the film carrier 20. The cut marker 46 is composed of a device for recording the triangular cut mark 47 shown in FIG. 3 on the side edge of the negative film 15 by thermal transfer recording. However, in addition to this, a punching machine for punching small holes may be used. Good.

The controller 33 is composed of a well-known microcomputer, which is connected to a keyboard 33A for inputting various commands and exposure correction data and the like, and a display 33B for displaying the input data and command contents. Have been. The controller 33 controls each part in order to automatically feed the negative film 15, print exposure, and specify a cutting position.

The operation of the present embodiment will be described below while explaining the processing procedure of the controller 33 with reference to FIGS. 4 and 5.

First, the tip of the negative film 15 is set on the film entrance side of the first feed roller pair 30. The controller 33 detects this film leading edge set based on the film detection signal from the film sensor 34. Then, the pulse motor 31 is driven to rotate the film feed roller pair 30, and the negative film 15 is fed toward the print position 19. During the film feeding, the controller 33 counts the number of drive pulses of the pulse motor 31 to detect the film feeding amount from the time when the leading end of the film is detected. In addition, the controller 33
Feeds a fixed amount of film from the time when the screen sensor 38 detects the screen to print the frame of the negative film 15 at the print position 19
Set to. The controller 33 is a negative film.
The frame number bar code 15C recorded on the side edge of 15 is detected by the bar code sensor 39, and the frame number is specified from the film feed amount and this bar code detection signal. Regarding the identification of this frame number, JP-A-63-305336,
It is described in detail in JP-A No. 1-102539. The frame position data of each frame thus obtained is temporarily written in a predetermined area in the memory 40.

After setting the frame at the print position 19, the operator observes the image of the frame and inputs the exposure correction data through the keyboard 33A as necessary. When the frame position is displaced from the print position, the fine adjustment key of the keyboard 33A is operated to adjust the position of the frame position. In this case, the controller 33 corrects the frame position data by the fine adjustment amount.

Further, the exposure correction data is sent to the exposure amount calculation unit 44 via the controller 33. In the exposure amount calculation unit 44, after calculating characteristic values such as LATD and color correction coefficient based on the photometric value from the scanner 43, the exposure amount control value is calculated by a known calculation formula using these characteristic values and exposure correction data. Calculate and send this to the controller 33. The controller 33 calculates the filter set position from the exposure amount control value using a well-known filter calibration curve, controls the filter adjustment unit 21 based on this position, and controls the shutter drive unit 45. As a result, the frame of the negative film 15 is illuminated by the printing light modulated by the filters of the respective colors, and the image of the frame is printed and exposed on the color paper 26. Then, the controller 33 also stores the exposure correction data at the time of negative verification in the memory 40 for each frame.

Next, the controller 33 frame-feeds the color paper 26 that has been exposed by printing, sets a new unexposed color paper 26 at the exposure position 27, and during this frame-feeding, prints the color paper 26 on the print frame. Correspondingly, the frame number of this frame is printed by the printer 28 on the back surface thereof. The controller 33 also feeds the frame of the negative film 15 in conjunction with the frame feeding of the color paper 26, and sets the next frame at the print position 19 by this frame feeding.

Thereafter, in the same manner, the images of the respective frames are printed and exposed on the color paper 26 one after another. During the printing exposure, the controller 33 counts the number of frames, detects the film feed amount from the time when the leading edge of the film is detected, and specifies the cutting position of the negative film 15 based on this. This cutting position is basically provided between the pieces so that the negative piece has a length of six pieces. However, in the case of the first negative piece, there is a blank feed frame, and since the blank feed frame differs for each camera model, the length thereof is not constant. Therefore, as shown in FIG. 3, in the case of the leading negative piece, the length is equal to or less than 6 pieces, and the first cutting position S1 is provided between the pieces 15A and 15A within this length. decide. Next, the second cutting position S2 is determined between the sixth frame and the seventh frame from the first cutting position S1, and the film cutting position is determined every six frames in the same manner. And the first cutting position
When determining S1, calculate how many frames the final negative piece will include when cutting every 6 frames one after another based on this first cutting position S1, and calculate the final negative piece by one frame. In such a case, the first cutting position S1 is set between the frames one frame before the initial position so that the final negative piece includes at least two frames. This is a negative piece of only one frame,
This is because the negative piece becomes short, and it becomes difficult to automatically set the frame at the print position at the time of additional printing later, and this is done to avoid this.

FIG. 3 shows an example of the cutting positions S1, S2, .... The distances L1, L2, ... Between the cutting positions S1, S2, ... Are the film feed amount reference values for attaching the cut marks 47 to the cutting positions S1, S2 ,. The data of the cutting positions S1, S2, ... Are also stored in the memory 40 together with the frame position data.

Then, the controller 33 detects the feed amount of the film tip from this position with reference to the installation position of the cut marker 46, and when the feed amount reaches the feed amount reference value L, the film feed is stopped. Then, the cut marker 46 is driven to record the cut mark 47 on the side edge portion of the negative film 15. After this, the controller 33 moves to the next cutting position S2.
In order to record the cut mark 47 on the negative film 15,
The feed amount reference value L is updated from L1 to L2. Thereafter, similarly, the cut mark 47 is recorded on the negative film 15 at the next cutting position S2 based on the updated feed amount reference value L.

Further, the controller 33 edits to create a reorder slip after specifying the cutting position for one film, and based on this edit, the creation necessary for printing the reorder slip 12 as shown in FIG. The data is sent to the print printer 11. Editing is performed as follows. First, the frame number data and exposure correction data of each frame are divided into the cutting positions S1, S2 ,. Next, each piece of the data for one segment is moved to the film insertion opening 61A side of the negative sheet 61 and laid out in a right-justified state.

The print printer 15 prints and creates the reorder slip 12 based on the print data from the controller 33. As a result, the display column for each frame of the reorder slip 12 matches the arrangement of each frame when the negative piece 62 is stored in the negative sheet 61.
63 can be laid out.

FIG. 6 shows an example of the reorder slip 12 in the case where the negative film 15 of 24 sheets of full size is cut into five negative pieces 62 and inserted into the negative sheet 61. In each display field 63, a frame number 64, exposure correction data 65, and a sheet number entry section 66 are printed. Note that in FIG. 6, when printing exposure is not performed due to a defective frame such as out-of-focus as in the display field 63 of the 18th frame, the frame number and exposure correction data of this frame are not printed. Also,
In addition to the title part 67 and the note part 68, the reprint order slip 12
ID of the check tape 37 attached to the tip of the negative film 15
A film ID number portion 69 having the same number as the number is printed so that it can be distinguished from those of other orders. Instead of the ID number section 69, the order number to be printed may be entered together with the frame number on the back surface of the print photograph 29. The ID number section 69 is printed by the operator inputting the ID number using the keyboard 33A. Instead of this printing, the operator directly enters the ID number.
You may make it write a number.

The negative film 15 for which the exposure of all the frames has been completed is removed from the film carrier 20 and set on the well-known film cutting inserter 70, where the negative film 15 is cut at the recording position of the cut mark 47, and the negative piece 62 and And stored in the negative sheet 61. And after inserting all the negative pieces 62 into the negative sheet 61,
The negative sheet 61, the finished print photograph 29 and the reorder slip 12 are inserted into the DP bag 71 and given to the customer.
Instead of using the film cutting inserter 70, the operator may cut the negative film 15 with the cut mark 47 as a mark and insert the negative film 15 into the negative sheet 61.

When performing reprint printing, find the display field 63 of the same frame number printed on the reorder slip 12 from the frame numbers printed on the back side of each print photograph 29, and indicate the required number in the number entry section 66. Fill in the numbers and this reorder slip
It is only necessary to submit 12 to the photo lab together with the negative sheet 61, and it is possible to easily order an additional print. At the photo lab, a display field in which the desired number of additional copies of the reorder slip 12 is entered.
Look for 63, the negative piece 62 in the same position as this display column 63
Is taken out, the frame at the same position as the display field 63 is set at the print position of the printer, and the desired number of print exposures are performed. At this time, by using the exposure correction data 65 of the reorder slip 12, it is possible to obtain a print photograph with the same finish as the simultaneous printing.

In the above embodiment, the film carrier 20 is provided with the screen sensor 38, and each frame is automatically set to the print position 19 based on the screen detection signal of the film carrier 20, but instead of this, the frame of the keyboard 33A is set. The negative film 15 may be semi-automatically set by a fixed amount by operating the feed key. Also in this case, when the frame position is deviated, the fine adjustment key is operated, and the fine position key corrects the frame position data by the frame feed amount.

Further, in the above-described embodiment, the printer that prints on the blank sheet
It was designed to print the re-order slip 12 by using 11, but in addition to this, the common items such as the number entry section, the frame, the title section, the notes, etc. were printed in advance and printed. The sheet may be used to create a reorder slip.

〔The invention's effect〕

As described above, in the present invention, the cutting position is specified from the frame position data at the time of printing exposure, the cutting mark is attached to this cutting position, and the reorder slip is created based on the cutting position. It is possible to obtain a reorder ticket having the same arrangement as each frame arrangement when the film piece cut by the cut mark is inserted into the film sheet. Therefore, it becomes possible to introduce a frame number printing system similar to that of a large-scale development laboratory with a simple configuration in which a printing printer is added, and it is possible to easily make a reprint order. In addition, it becomes easy to find the frames for additional prints at the photo lab, and even when the additional prints are made, the exposure correction data used during the simultaneous prints are used, so that the duplicated prints have the same density and color balance as the photos at the same time. Can be finished.
